Rule #41
// Quick-release levers are to be carefully positioned.
Quick release angle on the front skewer shall be an upward angle which tightens just aft of the fork and the rear quick release shall tighten at an angle that bisects angle between the seat and chain stays. It is acceptable, however, to have the rear quick release tighten upward, just aft of the seat stay, when the construction of the frame or its dropouts will not allow the preferred positioning. For Time Trial bikes only, quick releases may be in the horizontal position facing towards the rear of the bike. This is for maximum aero effect.
